MEANS FOR CLOSING MILK-CANS.

SPECIFICATION forming part of Letters Patent No. 376,690, dated January l'7 1888.

' Application filed June 5, 1886. Serial No. 204219. (Model) metically close. the vessel, and then to be so fastened that this closed position or condition of the lid shall be maintained during any required period of time.

My invention comprises certain novel constructions and combinations of parts whereby the said object is effectually secured. Figure I is a plan view, Fig. 2 is a sid view, and Fig. 3 a vertical transverse sectional view, taken on the line of Fig. 1, representing my said inventionas applied to a milk-can. Figs. 4 and 5 are detail views, on a larger scale,representing certain parts of an apparatus embraced in my said invention. Fig. 6 is-a vertical section on the line 2 of Fig. 3, and Fig. 7 shows the cover in section.

A is the body of the milk-can or other vessel in connection with which my said invention is to be used, and Bis the lid or cover thereof. The said lid or cover rests upon the top of the usual neck or opening of the can or vessel,

and the relation of the said two parts maybe of any usual or suitable construction. Extended through the lid or cover-B is a shaft, 0, the ends of which are supported or journaled ference of the said lid or cover. Upon each end of this shaft is formed a cam or eccentric, b, the shape of which is more fully indicated in Figs. 4 and 5. a

Extended laterally from this shaft is a hasparm, D, the outer extremity of which is so shaped as to extend down upon and act in conjunction with a bracket, E, which latter isjattached to the can A. The hasp-arm and the bracket may be of any suitable construction and arrangement in relation with each other, so long'as they may be broughtin conjunction to secure the hasp-arm after the lid or cover has been put in place upon the can or vessel,

as represented in the drawings; and, as preferably constructed, the hasp-arm has ahorizontal lip, f, with a vertical hole therethrough, and the bracket is arranged horizontally to correspond with the position of this lip and has a corresponding hole therethrough, so that Screwed upon'or connected to the opposite sides of the neck or top of the can or vessel A are two lugs or cars, F, at the inner side of each of which is a shoulder, 9, provided with a downwardly-projectingstop, g, for limiting the axial movement of the lid when the shaft 0 strikes said step, as represented'more fully in Figs. 4 and 5. When it is desired to apply the lid or cover to close the can or vessel, the former is placed upon the latter,with the cams or eccentrics b in the position indicated in dotted outline in Fig. 1, and with the hasp-arni thrown over 'upon its back, as also indicated in dotted outline in said figure. An axial movement is then given to the cover to bring the cams or eccentrics under the shoulders g of the lugs or ears F, the cams or eccentrics I being in the position first described -i. 6., de-

pressed to permit them to pass-under said shoulders. The cams -or eccentrics being thus brought under the shoulders g, the hasp-armis turned over, thereby giving substantially half a turn to the shaft 0 and bringing the lip f down upon the bracket E. This movement of course turns the cams or eccentrics, so that they bear upward against the shoulder g, and consequently forces the lid or cover firmlydownward upon its seat, thereby 'hermetically'closing the opening or mouth of the can or vessel.

The shape of the cams or eccentrics is preferably such that they willretain their places when brought into position, as just described; but for the sake of security and the prevention of accidents it is preferred that a padlock or other suitable fastening device should be employed to connect the hasparm with the bracket.

The cover is cup shaped, an'd is therefore open at its top, so that its hasp arm-closing device works within the open top. The bearings of the shaft are formed in thimbles a, as seen in Figs. 3 and 7, so that the shaft can be easilyput in position before the thignbles are, and the latter are then riveted by their flanges to the cover, so that the cam ends of the shaft project out beyond the thimble-flanges. The packing-confining flange c is preferably a separate ring-piece soldered onto the cover at the shoulder formed in its vertical walls, and I prefer to stamp the cup-cover of sheet metal with such shoulder.

WVhat I claim as my invention isl. The combination of the vessel A, having flanged lugs F g, the cover 13, having the crossshaft C journaled therein, formed with end cams, the hasp D, secured upon said shaft and terminating in a lip, f, at its free end, and the fasteningbracket E for said hasp secured to the cam, substantially as shown and described. 2. The combination of the vesselA, having the flanged lugs F g, and the stop 9, the cover 13, having the cross-shaft journaled therein, formed with end cams, the hasp D, secured upon said shaft and terminating in the lip f, and the fastening-bracket E for said hasp, substantially as shown and described.
